| Abstract | This article reviews emerging technologies in wireless communication systems, focusing on their key concepts, principles, use cases, and challenges. It examines relevant studies in the telecommunication sector, with a focus on technologies that enhance connectivity, performance, and innovative applications across industries. The review highlights advancements such as fifth-generation (5G) networks, which offer faster data speeds, lower latency, and increased network capacity, enabling the development of applications like autonomous vehicles, smart cities, and Internet of Things (IoT) devices. IoT devices are increasingly connecting physical objects, driving innovation in sectors such as healthcare, agriculture, transportation, and manufacturing. Edge computing, by enabling real-time processing and reducing latency, supports IoT applications requiring immediate responses. Artificial intelligence (AI) and machine learning (ML) are being integrated to optimize network resources, improve spectrum management, and facilitate intelligent decision-making. Technologies such as massive multiple input, multiple output (MIMO) enhance spectral efficiency, network capacity, and interference reduction. Millimeter wave (mmWave) frequencies are being explored for high-speed wireless communication, enabling multi-gigabit data rates and applications in 5G, wireless backhaul, and ultra-high-definition video streaming. Software-defined networking (SDN) and network function virtualization (NFV) enable centralized management and greater network flexibility, while beam steering improves signal quality and coverage by directing wireless signals toward specific receivers. Quantum communication, leveraging quantum principles, provides secure communication channels, while quantum key distribution (QKD) ensures data confidentiality. Visible light communication (VLC) utilizes visible light for high-speed data transfer in environments where RF-based communication is not feasible. Despite the potential of these technologies, the article identifies challenges such as limited practical implementation, standardization issues, resource constraints, security and privacy concerns, and sustainability challenges. It concludes by discussing the practical implications of these emerging technologies, including enhanced data transfer speeds, improved network capacity, low-latency communication, IoT connectivity, ubiquitous coverage, industry transformation, and the security and privacy considerations that accompany these advancements. © 2025 World Scientific Publishing Company. |
